Cortana is an intelligent personal assistant created by Microsoft for Windows 10, Windows 10 Mobile, Windows Phone 8.1, Microsoft Band, Xbox One, iOS, and Android.

2. Navigate to the following settings:
Computer Configuration > Administrative Templates > Windows Components > Search
3. From the right-side pane, double-click on “Allow Cortana”.
“This policy setting specifies whether Cortana is allowed on the device.
If you enable or don’t configure this setting, Cortana will be allowed on the device. If you disable this setting, Cortana will be turned off.
When Cortana is off, users will still be able to use search to find things on the device.”
4. Set the settings to Disabled, click Apply and Exit.
